$NBIS rose 10.78% Tuesday as AI-infrastructure names rallied after Anthropic's preliminary IPO filing, while refiners took the other side of the tape.
- Nebius (+10.78%, $40.8B) and Astera Labs (+9.86%, $49.3B) advanced on Anthropic's preliminary IPO filing and a lender group's agreement to finance a $63B purchase of Broadcom AI chips for Anthropic.
- Cerebras rose 9.89% after Oracle said it will add Cerebras hardware for AI inference on Oracle Cloud Infrastructure starting in the first half of 2027.
- AMD gained 5.44% on heavy volume after committing a $1B investment in Meta's equity offering under an expanded AI-infrastructure partnership; Nvidia is investing $3B in the same raise.
- Refiners fell as crude climbed on an Iran/Israel risk premium: Valero -8.18%, Marathon Petroleum -6.62%, Phillips 66 -6.25%, with PSX reporting Q3 before Wednesday's open.
- Breadth: semiconductors +2.83% with 11 of 11 higher; oil and gas -3.33% with 0 of 7 higher. SMH +2.93%, XLE -1.89%.
Valero's history offers context: across 38 drops of 8% or more in 19.8 years, 62% were higher three months later, at a median +16.4%. Wednesday's Phillips 66 results will show whether margin pressure is showing up in reported numbers.
